    We called and spoke with Angela/Rhonda in the office and (Steve) Sales Representative was scheduled to come to our home for a Furnace & A/C Quote. Steve was so knowledgeable and KIND. Because we have used Thielman over 20 (twenty) years, we TRUST their Honesty & Integrity. We were scheduled in 1.5 weeks to begin the work.

    Awesome service and job completion. Jake came right away and worked tirelessly to diagnose the issue. Found the issue, very informative, got the pets, installed. I was shocked at the cost in a good way. Thielmann is the BEST!!!!

    We had problems with our home boiler system. I had Thielmann come in and quote me a new system. The person who came was extremely knowledgeable (Steve). After recovering from sticker shock we contracted them for the job. They were able to schedule us within a week. They were in and out in less than a day. Cleaned up everything. Installers were very professional. New system seems to be a winner. Office staff was pleasant too...as they took my $$...loll. Highly recommend!
